Red Bull urges FIA to act on Mercedes domination

After a frustrating weekend for the Renault-powered team, Horner has called for action to stop fans from losing interest in the sport because one team is clearly ahead of its rivals.
Mercedes dominated the 2014 season, winning 16 of the 19 races, as its cars and power unit proved a cut above the rest.

We are probably 100hp down on Mercedes at the moment.
